Yes defiantly will fit. Uni bodies or not makes no difference. Nissan product is full frame. Bumper comes off Infiniti QX4/pathfinder and gets welded directly onto rodeo. Only welded with a 9/16" gap to allow for the curvature of the bottom of 00-04 grills . Fender flares should line up or be close enuff. Hell even a Montero sport bumper will bolt up. Toyota 4 runner too. Come on remember the old lowrider Mimi truck days. People were switching out bumpers from Toyota 4 runners and installing them on there Isuzu lowrider space cab pickups. So what would be the difference?? Answer is.... nothing
